ted, displayed, and exported. A limit check is performed only for those harmonics for
which a limit value is defined.
Sample file
A sample limit file is provided on the instrument:
C:\Users\<user_name>\Rohde-Schwarz\RTH\Harmonic\LimitExample.csv
The file format is a comma-separated list (.csv). At least the following contents must
be included:
Header:
<Device>,Version,<file_version>
Harmonics,Limit[%]
Values:
<Order of harmonic>, <limit value in % of fundamental>
●
Comments introduced by "#" are allowed.
●
If a limit is not provided for a harmonic, the harmonic is displayed and its results
are included in the export, but not in the limit check.
●
The fundamental is always displayed and need not be included in the list.
Example:
RTH,Version,1.0
Harmonics,Limit[%]
2,10.5
4,0.004
20,3.7
10
13,0.01
3,0.01
5.3.6.2 Harmonic Results Export File Format
The harmonic results export file format is similar to a waveform export file; it is also
stored in CSV format. You can convert the comma-separated text to columns (see
Chapter 11.4.3.3, "Converting CSV to Excel Files", on page 229).
The harmonics results file contains some general header data and then a set of result
data for each harmonic. A maximum of 64 results can be provided, but the actual num-
ber of harmonics may be restricted (see "Limits, Loaded File" on page 132). Each set
of data contains the results for a specific harmonic in each input channel.
